NITED STATES PATENT OFFICE.

ARTHUR OBRIEN, OF HELENA, MONTANA, ASSIGNOR OF ONE-FOURTH TO MARTIN A. MITCHELL, OF SAME PLACE.

SANITARY APPLIANCE.

SPECIFICATION forming pari'. of Letters Patent No. 665,926, dated January 15, 1901.

Application filed August 5, 1898. Serial No. 687,797. (No model.)

To all whom it may concern,.-

Beit known that I, ARTHUR OBRIEN, a citizen of the United States of America, and a resident of the city of Helena, county of Lewis and Clarke, State of Montana, have invented certain new and useful Improvements in Sanitary Appliances, of which the following is a specification.

My invention relates to the sanitary appli- Io ances commonly known as traps and to the method of attaching them to the fixtures, such as sinks, bowls, bath-tubs, and the like. Its merit lies in its simplicity,the small number of parts, cheapness ofconstruction, and

I5 easy accessibility for cleansing.

In the accompanying drawings,Figure I represents a plan View of mytinvention with the stopper removed. Fig. II shows a side elevation in section.

. zo Similarletters refer to similar parts in both views.

A is the fixture, bowl, sink, bath-tub, or the like.

G is a ring having a flange la and threaded z5 on the inside.

B is the trap-cylinder, closed at its lower end, having the threaded discharge orifice or pipe E, and contracted and threaded at its upper end at h to screw into the ring G.

3o D is the trap-pipe, having the narrow flange ol.

C is the follower, having the cross-bars c c and threaded on the outside to screw into the ring G.

E is the stopper.

fand g are washers of rubber or other suitable material.

Having thus described the various parts, the construction and action are evident. The

4o rings G are made ot' various sizes to lit the outlets of varioussized xtures and can thus be quickly fitted to any fixture. Thus the ordinary coupling and lock-n ut are done away with, the ring forming the single connection between the trap and the fixture. The joint of the ring G with the fixture A is sealed in the ordinary way with white lead or putty, and when the trap-cylinder B is screwed into the ring G, compressing the washer f between the shoulder of the trap-cylinder B and the 5o bottom of the iixture A, the joint is made perfectly tight. The trap-pipe D is then placed Within the trap-cylinder, its flange d nding a seat on the washerg on the upper edge of the trap-cylinder B. The follower C is screwed to its place, making the joint tight at d. The usual sealing against sewer-gas is `accomplished in the usual way by the water `rising in the trap-cylinder and trap-pipe to the lower edge of the discharge-pipe F. 6o

In this invention the least possible space for the accumulation of gases between the surface of the sealing-water and the orifice of the fixture is secured and amore or less complicated arrangement of couplings and nuts is avoided. The cleaning of the trap is simplicity itself. The follower C is unscrewed andthe trap-pipe withdrawn, when the whole trap is open for cleaning and inspection. In case of corrosion or injury of the trap-pipe, 7o a new one is readily inserted at a minimum of cost and labor as compared with present methods.

I- do not confine myself to the particular form of trap-cylinder shown nor to the particular method of securing the trap-pipe shown'. The follower and trap-pipe may be in one piece, thus lessening the number of parts and simplifying their removal and cleansing.

Having thus described my invention, what 8o I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the fixture of a sanitary appliance forming a combined trap and connection, consisting of a ring having '85 atop ange outside and threaded inside,a trap-cylinder having a discharge-pipe and threaded outside at its upperend, a trap-pipe having a ange and a screw-ring at the upper end thereof to hold the flange of the trap- 9o pipe to'bear upon the top of the trap-cylinder substantially as described.

2. The combination with the fixture'of a sanitary appliance forming a combined trappipe and connection, consisting of a ring having a top flange outside and threaded inside upon lshe top of the trapeyliuder substantially as described. 1o
